DAVID S. KENNEDY, OF BROOKLYN, NEW YORK, ASSIGNOR T0 MERGENTHALER LINO'I'YPE COMPANY, A CORPORATION OF NEW YORK.

TYPOGRAPHICAL MACHINE.

To all whom it may concern:

Be it known that I, DAVID S. KENNEDY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York,have invented certain new and useful Improvements in Typographical Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographical machines, such as linotype machines of the eneral organization represented in Letters atent of the United States to O Mergenthaler No. 436,532, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a slotted mold, the mold filled with molten metal to form a slug 0r linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned through distributing mechanism to the magazine from which they started.

In these machines as ordinarily constructed, the size of the matrices is considerably limited, and it is seldom attempted to employ therein matrix fonts above 18 pt. There has long been a demand in the trade for machines capable of handling matrices of larger size, and many efforts have been made to meet such a demand. Thus, a special machine has been designed to permit the use therein of matrices assembled or set up by hand in a stick or holder which may be inserted manually in. the machine, it being possible in that way to employ matrices of the desired size. These special machines, however, have failed to meet the demands of the trade because they lack the numerous advantages of the regular automatic linotypes, so that other efforts have been made to adapt these latter machines to the new conditions. Thus, it has been proposed to divide an individual matrix font among two regular magazines, devoting each entirely to one-half thereof, but this arrangement is objectionable for obvious reasons, necessitating the use of two distinct distributors, and leading into other complications. It has also been proposed to split the individual matrices of a font in halves and to run the complementary sections of such matrices in the same magazine channels in order that characters of the required width may be Specification of Letters Patent.

Application filed October 8, 1919. Serial No. 329,339.

used, but this arrangement is likewise unsatisfactory. Various otherschemes have been suggested, but it would unduly prolon this specification to discuss them here. Suf fice it to-say, that of all prior arrangements, none has completely solved the difficulty.

In my companion application Ser. No. 329,238, there is presented an automatic machine of the regular type which has been found in actual practice to answer completely the various requirements of the trade. This improved machine is not only capable of handling 18 pt. matrices, but matrices of a much larger size, up to 30 pt. wide, and this without changing the normal size or dimensions of the other machine elements, which .it is desirable and important to preserve. That is to say, in my improved machine, the various parts have not been widened or extended (as might be done and as would naturally occur to one) in order to make use of matrices of the increased size, but they have been so modified otherwise that they will be adapted to handle the larger matrices. The various improvements by which these results are attained are fully pointed out in said companion application, to which reference may be had for fulldetails.

My present invention is directed more particularly to a machine of the class just referred to and contemplates certain improve ments designed to increase the capacity of such machine still further, as will be fully set forth in the detailed description to follow.

I have herein shown my invention merely in preferred form and by way of example, and obviously many changes and variations may be made therein without departing from its spirit. I therefore desire it to be understood that I do not limit myself to any specific form or embodiment except in so far as such limitations are specified in the claims.

The matrices X or Z are stored in the channeled magazine A and are released therefrom by the escapements E (Fig. 2)

under the influence of the keyboard E,

whencethey pass through the channeled front plate or raceway B onto the inchned conveyer belt B, which delivers them to the illustrated in Fig. 5,

assembler B wherein they are composed in which releases them at different points in its length according to character and drops them intoa channeled magazine-entrance D or F for return to their proper channels in the magazine. The magazine A is supported upon the baseframe A which is arranged to be swung upwardly to disengage the magazine from. the underlying bank of escapements E (whose supportlng bar A is mounted in the fixed machine frame) and locate it above the front-plate B, as shown by the dotted lines in Fig. 2, when it may be drawn forwardly from the front of the machine. To effect this swinging of the base frame A it is pivotally mounted at its upper end upon the transverse rod A and is provided at its lower end with the pair of cams A fast to the opposite endsof the transverse rock shaft A. journaled in the base frame, the cams being arranged to cooperate with the rollers'A on the machine frame and being operated by the arm .A fast to the rock shaft A all as shown and described in detail in either of the patents to T. S. Homans, Nos. 814,542 and 829,969.

In the companion application before referred to, there are set forth certain improvements intended to provide for the use of matrix fonts up to say 30 pt. wide.

Generally speaking, such matrix fonts (herein designated X) comprise but seventytwo'characters as distinguished from ninety characters of the ordinary fonts, the characters eliminated being those of the combined letter variety such as fi, fi, ffi, etc., and a few miscellaneous characters; and the space which would otherwise be taken up by these omitted characters in the different parts of the machine is utilized to enlarge the space devoted therein to the remaining characters of the font in such manner that the individual matrices may be increased in thickness in proportion to. the additional space afforded by the reduced number of characters. Y

Referring first to the magazine A, it is of the regular trapezoidal shape and 'is provided on the inner faces of its top and bottom plates with series of ribs a presenting sets of opposing grooves a (Fig. 5), which converge from the upper to the lower ends thereof and provide channels wherein the projecting ears X gage. As shown, there are seventy-three such grooved channels a, two for the letter e and one for each remaining character of the new font, and these channels as so reduced in number are spaced apart throughout the entire width of the magazine. As the grooved channels of the matrices X enfont, those at the lower end of the magazine being located to provide for the discharge of the matrices from the respective channels without interference, and those at the upper end thereof being located to provide for the distribution of the matrices into said channels. It is pointed out, however, that in determining these points, the increased space afforded by the reduced number of channels (namely, seventy-three) is divided or apportioned among them at both their lower and upper ends, not equally, but proportionately according to the varying set widths of the different characters of the largest matrix font, so as in this way to take full advantage of the increased space.

Although differing radically in number and arrangement of its grooves a the magazine A is the same in size or width throughout as the standard or regular Model 5 magazine now in general commercial use. The difference in the number and arrangement of the grooves is illustrated in Fig. 7, which shows at the discharge end a portion of the improved magazine A in comparison with a similar portion of a Model 5 magazine Y, which latter of course is formed with ninety-one sets (the standard number) of grooves 3 spaced apart in the usual manner. From this comparison, it will be seen that, due to the. novel spacing of the grooves of the im roved magazine, the size of the matrices l (lower case) stored therein is considerably greater than that of the usual matrices W contained in the regular magazine, although both magazines are of the same width. This difference is even more pronounced with the upper case matrices.

.The increased space thus provided in the magazine A amounts approximately to 25% and when apportioned among its channels as above described enables them to accommodate matrices of corresponding increased size.

As the magazine A is of the same width at its receiving end as the standard or regular Model 5 magazine, as above described. the magazine-entrance D may be and is of the same width as the regular ninety-one channeled magazine-entrance which cooperates with such standard magazine, but the number and arrangement of the partitions (Z which divide it into matrix channels have been changed so as to provide but seventythree such channels, one for each channel of the magazine and of a width suitable for matrices passing therethrough. That is to say (Fig. 5), the partitions d when thus re- (ll1( ed in number are spaced apart throughout the entire width of the entrance and are separated different distances from each other so as to apportion the full space of the entrance among the seventy-three intervening channels in accordance with the set Widths of the different characters of the largest matrix font, it being remembered that the magazine grooves a are unequally spaced apart at their upper ends to correspond with the varying widths and locations of the entrance channels. In the present instance, then, the increased space afforded by the reduced number of entrance channels is divided or apportioned among them proportionately according to the varying set widths of the different characters of the largest matrix font.

Similarly, the distl'ibuter bar C is of the same length as the regular ninety-one combination bar employed in connection with the Model 5 magazine and magazine-entrance. However to adapt it to its new conditio'ns, the bar is formed with only seventy-three combinations 0, one for each channel of the magazine and magazine-entrance, and these combinations are spaced apart throughout the entire length of the bar, and at unequal distances, so as to correspond with the location of the entrance channels. That is to say, the increased space afforded by the reduced number of bar-combinations is divided or apportioned among them proportionately according to the varying set widths of the different characters of the lar est matrix font.

f he entrance D is provided with supplemental guiding means to engage the matrices as they pass therethrough and direct them in proper position and under positive control into the proper channels of the magazine. .Such means are presented in the Butts Patent No. 1,099,486 and are embodied herein in precisely the same form for most of the channels, consisting of guiding surfaces or bent over flanges d projecting in pairs into the entrance channels from the partitions (l in position to engage the projecting ears X on the opposite edges of the matrices X. Hence, and as more fully brought out in the Butts patent, the individual matrices, though of varying thicknesses in the different fonts, will be guided from the entrance channels in a straight or upright condition and caused to enter the magazine grooves in proper position.

However, there is a further difficulty arising from the use of extremely wide entrance channels which has had to be overcome. When the thin matrices are run through these wider channels, they are apt to topple over so far that their projecting ears will not be engaged by the guiding flanges d. This condition is illustrated in Fig. 4, which shows by the full lines a thick matrix under control of the flanges and by the dotted lines a thin matrix which has passed beyond their control due to the abnormally inc ined position which it can assume within the entrance channel (see also Fig. Such a thin matrix, therefore, may jam and cause a piling up of the succeeding-matrices. To

overcome this difliculty, the guiding surfaces of the guiding flanges d to such extent that while the larger matrices may pass freely therethrough, the thinner ones will be prevented from falling over so far as not'to present their projecting ears to the guiding action of the flanges, this being brought about, of course,-by the tongues 03 which guide the matrices by their side faces until their projecting ears become engaged by the flanges. These tongues are further advantageous in thattheypermit the use of a single partition as the side-walls for adjoining entrance channels when otherwise extra partitions might be necessary, and in general they allow the channels to be made wider for any purpose. In addition, the tongues serve to contract the widths of the entrance channels without altering the positions of the partitions constituting the side-walls thereof, which feature is particularly useful when it is desired to change the width of one channel without affecting the width of the adjoining channel, as would necessarily result by the adjustment of the partition itself.

The foregoing and various other improvements are described in great detail in the companion application Serial N 0. 329,338 above mentioned, and it would therefore be superfluous to discuss them further herein.

As before explained, the present invention is directed more particularly to certain improvements in the class of machine above discussed. The improvements first to be described are intended to adapt the parts in their present form to handle matrices of the larger sizes, 2'. 6., above 30 pt., thus increasing the ca iacity of the machine to its fullest extent.

fonts of matrices characters are employed," the additional space afforded by the elimination of the seventeenfurther characters (which arethe figures and a few miscellaneous characters as indicated by the shaded key buttons in Fig. 19) being utilized to increase still further the size or thickness of the individual matrices. In this instance, the desired ren carrying out this feature,

Z comprising only fifty-five sults are realized by altering theusual form of the matrices an by employing a further magazine-entrance which may be substituted for the entrance D when desired.

In Fig. 9?, a group: of matrices Z is shown at the left and a similar group of matrices X at the right. As will be apparent, the

latter matrices which are of usual form exprojecting ears Z and tooth-combinations Z located in different setwise positions on the respective matrices of the font, the location of the ears being different from and independent of that of the combinations, for reasons which will later appear. Bythus varying the setwise positions of their projecting ears, the matrices Z of a given font may be stored in the magazine A so as to occupy the entire space accorded by its full width. Such a magazine with the contained font is shown in nd view in the diagram of Fig. 19, wherein the different relative positions of the projecting ears on the respective matrices of the largest font above 30 pt. are clearly indicated. Itwill be observed that as so arranged, certain of the matrices Z occupy single channels as before and others two or more channelsin whole or in part, the body portions of the matrices extending both to the left and'right of the projecting ears Z due to their different setwise positions thereon. In this way, the entire space of the magazine may be devoted to and apportioned among the fifty-five columns of matrices, which may consequently be increased in size or thickness in proportion to the space so gained,'amounting approximately to 32% as compared with the seventytwo character fonts and to 57% as compared with the regular ninety-character fonts.

Fig. 7, for the'sake' of comparison, shows is apparent. It may be noted at end vi ew portions of two magazines A, one containing the matrices within the magazine indicate the character arrangement of these fonts. This different character arrangement of the matrices Z has been resorted to in order that they may be stored to the best advantage in the grooved channels of the magazines A and discharged therefrom without interference.

Referring now to the special magazine- 'entrance F, which is employed in connection with the matrix fonts Z, it (like the entrance D), is of normal width and is provided with partitions 7' spaced throughout-- its entire width and dividing it into matrix channels. In this instance, however, there are but fiftyfive channels, one for each character in an individual font (there being no double e channels) or for each matrix column in the magazine, and the widths of these channels vary relatively in accordance with the set widths of the different characters of the largest matrix font. Now, as ordinarily, the partitions (I of the entrance D (see Fig. 5), are located in vertical planes passing substantially through the releasing points of the bar combinations 0. While such an arrangement is suitable for matrices of usual form, such as the matrices X, (whose projecting ears X are located in the same setwise positions on all of the matrices of an individual font and whose body portions 4 extend only to the left of such projecting ears, Fig. 7), it is entirely unsuitable for the matrices Z, which in some cases not only lying in 66 thatmany of the partitions (like occupy more than one magazine channel but whose body portions extend both to the left and right of their 1grojecting earsZ, as before mentioned. vence, to adapt the entrance F to the matrices Z of such different form, its partitions 7' are arranged in different. positions with reference to the-magazine ribs a} and the bar combinations 0, some being located in and others out of registry with the magazine ribs, and some vertical planes passing through the releasing points of the bar-combinations, and others lying in vertical planes offset from such combinations atone distance or another; The effect of this arrangement is that the entrance channels occupy varying relations, not only to themagazine grooves a, but also to the bar combinations 0, these varying relations enabling the channels to communicate with and in such manner that the matrices ma be conducted through the channels with their projecting ears in position to enter the required set of grooves. The specific arranlgement of the partitions f is best shown in ig. 9, wherein the releasing points of the corres onding bar combinations 0 are indicated by the dotted lines, and wherein the extent of the lateral displacement of the various partitions is clearly shown. It will be noted, however,

the ordipartition may not conveniently act as a common wall for both.

The foregoing arrangement of the entrance partitions is permitted and provided for by varying the setwise positions of the tooth-combinations Z on the matrices Z as before referred to. positions of the tooth-combinations throughout the largest individual font above 30 pt. are indicated in Fig. 9, which for the purpose shows all of the matrices of the font as in the process of distribution. For the sake of clearness, however, the tooth-combinations themselves are not shown, but their different relative positions on the respective matrices are indicated by the longer dotted lines which are extended downwardly from the releasing points of the active'bar-combinations c, the shorter dotted lines indicating the releasing points of the inactive combinations or those not used for the matrices Z. It will be observed that in most instances the tooth-combinations are located at or flush with the rear sides of the matrices as customary, the partitions having been arrangedto permit this wherever possible, but in many instances, the tooth-com- 'binations are located toward the center of the matrices or away from the rear sides thereof so as to drop them into the corresponding entrance channels, whose left or rear side walls are displaced laterally from the releasing points of the respective barcombinations. In the present arrangement the tooth-combinations Z are changed to correspond with the character arrangement of the matrices Z in the magazine and'consequently differ from those of the matrices X as well as those of the ordinary ninety-character fonts, thus following the common practice of rearranging the matrix combinations. Since some of the bar-combinations, as above indicated, will not be used in the distribution of the matrices Z, it will be understood that the foregoing remarks concern only the remaining or active bar-combinations whose relation to the entrance channels determine the setwise positions of the tooth-combinations on the matrices Z. In view of the above construction and arrangement of the parts, when a magazine containing a font of matrices Z is inserted in the machine, it

These different setwise tribution of the matrices will be insured. In other words, by interchanging the magazine entrances D and F, the machine may be adapted to handle any desired font of matrices.

To effect this interchange of the entrances, they are movably mounted in such manner that either may be brought into operative relation to the distributer and the selected magazine at will. The entrance D (Fig. 8) is pivoted by a stud D to the magazine baseframe A so as to be swung downwardly to inoperative position or upwardly to operative position, a spring D being employed to hold it yieldingly in the latter position. The entrance F, on the other hand, is pivoted at opposite sides by studs F to a pair of arms F 2 fast to a rock shaft F which is journaled in the lower ends of arms F pivotally suspended from a transverse rod F of the framework, the whole constituting a swingin frame which may be turned about the rod 5 as an axis to locate the entrance in operative position, as shown by the full lines in Fig. 6 or in inoperative position as shown by the dotted lines in said figure. It is held in the latter position by a detent F located on the framework in position to engage in an opening F in one of the arms F. When in its operative position, the entrance is locked to the magazine base frame A- by detents F passing through the pivot studs F and engaging in recesses in the outer ends of the pivot studs D of the entrance D (Fig. 8). The two pairs of arms F 2 and 'F (constituting respectively the lower and upper sections of the frame) are formed with stop shoulders F which in the normal position of the parts are held in engagement by springs F, one attached at its opposite ends to the two arms of one pair, and-the other connecting the upper arm F of the second pair with a lug F projecting laterally from the entrance, said lug being adapted to engage the lower arm F of such second pair and thus to limit the pivotal movement of the entrance in one direction. By reason of this construction, the entrance F may be freely turned within its supporting frame to and from operative position while said frame is locked to the magazine base frame. Similarly, the magazine base frame is free to be rocked upwardly to permit the removal of the magazine without unlocking the entrance framewhich at such time yields through the relative movement of the arms F and F (see dotted lines in Fig. 6). The manipulation of the entrances will now be clear. When a magazine containing a font of matrices X is inserted in the machine, the entrance D is swung to operative position and the entrance F to inoperative position, as in Fig. 2,; whereas, when a magazine containing a font of matrices Z is substituted, the entrance F is brought to operative position and the entrance D thrown down to inoperative position, as in Fig. 6. v

As the matrices Z also vary in thickness according to font, it is desirable toprovide the entrance F (like the entrance D) with supplemental means. to into the appropriate magazlne grooves. To this end (Fig. 9), the partitions f are provided at their lower ends with guiding surfaces or bent-over flanges 7 which are arranged to engage the projecting ears Z of the matrices and guide them positively into the correct set of magazine grooves a. As shown, some of the channels have but one set of guiding flanges, whereas others are provided with two sets of such flanges. Vhen equipped with a double set of flanges, the channels are enabled 'to discharge the matrices therefrom in correct position independently of the partitions I, which therefore are not requiredto be flush with the straight side walls of the magazine grooves a, as would otherwise be necessary in handling the thinner matrices. Some of the partitions f are also formed 'with leaf sec tions or tongues f (identical with the tongues d carrying the guiding flanges f and which gradually diminish the widths of the appropriate channels to adapt them to take care of the thinner matrices passing therethrough, nection with the matrices X, although the advantages previously mentioned are even more pronounced in the case of these leaf sections or tongues The manner in which the matrices are released from the magazines will now be described, reference beinghad to Figs. 10 to 19. It has already been pointed out that the matrices Z of the larger or fifty-five character fonts are arranged in the magazine in a different order .ascto character from that of the matrices Xfof the smaller or seventy-two character fonts, so that these fonts not only differ as to number of characters but also as to character arrangement of the matrices in the magazines. The present improvements provide means whereby the key-board E may be operatively connected to the magazine in use, whether it contains a font or matrices X or a font of matrices Z, and in such manner that the finger keys will effect the release of the matrices bearing the same character in either case, a feature which I believe to be broadly new. In the embodiment illustrated, the keyboard comprises but seventy-two keys, one for each. character of the matrix font X, and the intermediate parts are reduced to correspond.

Referring now in detail to the construction of the parts (Fig. 2), the escapements E one for each channel of the magazine, or seventy-three in all, are actuated in the usual way by the corresponding series of guide the matrices precisely'as described in conreeds E (Fig. 10), which in turn are operated by the yokes E arranged in banks and provided with the cams or eccentrics E adapted under the influence of the trip dogs or triggers E to cooperate with the underlying-power driven rolls E, the triggers being controlled from the finger keys E in a manner presently to ,be described. This arrangement of the parts is illustrated diagrammatically in Fig. 19, and it will be noted that the finger keys and intermediate parts lie substantially in the vertical planes of the corresponding magazine channels, as usual.

The mechanism through which the finger keys E act in effecting the operation of the cam yokes comprises two series of slides E, E and a series of U-shaped rocking bails E (Figs. 10 and 12). The slides E, E, are disposed in pairs, one for each finger key and its respective trip dog E, and are arranged to be shifted laterally so as to be alternately engaged with the corresponding finger keys. The bails E are located in rear of the slides and are disposed in superposed groups, one for each bank of finger keys, the bails of each group having their parallel arms separated different distances and arranged to cooperate with different pairs of slides in such manner that when the slides are shifted laterally, those of one series will be engaged with the corresponding finger keys and the contiguous arms of the associated bails, and those of the other series engaged only with the other arms of the bails, and vice versa. To provide for such engagement of the parts, the slides E, E, are formed in their forward edges with notches e wherein the finger keys engage, and in their rear edges with notches e wherein the arms of the bails engage, it being noted that the notches e of the slides E are wider than those of the slides E for reasons which will presently appear (Figs. 16-18).

The slides E are employed to make up a series of direct connections between the finger keys E and the escapements E in effecting the release of the matrices X from the magazine, while the slides E through the medium of the bails E and other slides E are utilized to make up another series of indirect connections between the finger keys and the escapements in effecting the release of the matrices Z. Accordingly, the slides E are extended sufliciently to make connection with the trip dogs E, being formed at their upper ends with notches e wherein the dogs engage, which notches are of such lateral extent as to maintain their engagement with the dogs in either position of the slides (Fig. 13). On the other hand, the slides E stop short of'the tri dogs so as to be entirely free thereof. ence, when the finger keys E are engaged with the slides E (Figs.

12 and 17), the latter throu h their direct connection with the trip dogs 5 through the associated cam yokes E into action and cause the operation of the escapement actuating reeds E the bails E at this time being unaffected due to the presence of the widened notches e of the slides E. In this condition of the parts, the finger keys are' connected directly to the magazine, and in the usual manner, each finger key and the intermediate parts being located substantially in the same vertical plane as the corresponding magazine channel. When, however, the finger keys are engaged with the free slides E (Figs. 18 and 19), the latter do not affect the overlying cam yokes but, through the medium of the bails E", transmit the motion of the keys to the active slides E of other cam yokes, which are thus thrown into action to operate the escapement reeds E located thereabove, it being remembered" that the active slides, -though disengaged from'their corresponding finger keys, still maintain their connection with the cam yokes. In this condition of the parts, the finger keys are indirectly connected to the magazine so as toeilect the release of the matrices in the required manner, the finger keys being located in planes offset at various distances from the matrix columns with which they cooperate in accordance with the character arrangement of the matrices in the magazine.

By referring to the diagram of Fig. 19, it will be noted that except in the case of the comma, every one of the matrices Z occupies a different channel in the magazine from that of the matrix X bearing the same character. Since the location of the commamatrices is unchanged, the same connections from the finger key may be used for all fonts. In such case, therefore, and as no bail is required, the slides E, E of the corresponding pair are directly attached or made integral, so that the finger key is permanently connected to the associated cam yoke and throws it into action in either position of the slides. In the case of the remaining matrices, however, they will require the use of the bails E so that fifty-four of such bails are provided, each being arranged to connect the associated finger key to that escapement serving the magazine channel wherein the matrices Z bearing the same character are stored. This condition of the part-s is illustrated in Fig. 19 (the key buttons of the unused keys being shaded), but for the sake of clearness only one group of bails is illustrated, namely, that for the third row or bank of finger keys, it being understood that these bails in their mechanical embodiment are all located at the rear of the slides at the same level and upon a common pivot (see Fig. 12). The connections from any one ot the keys may be easily traced:

Taking the letter a, for instance, its finger key is engaged with the associated, free slide.

E, which is connected by the relatively short bail E to the active slide E associated with the left thereof. Such active slide, though disengaged from its finger key, maintains its connection with. the tri dog E, which therefore, in response to t e actuation of the a fingerkey, throws the connected cam yoke E into action to operate the actuating reed E for the escapement E of the magazine channel wherein matrices X bearing the letter .e are stored and which is'now occupied by matrices Z'bearing the letter a, Similarly, inthe case of the letter r, its finger key is enga ed with a free slide E which is connected (extending more than half way across the keyboard) to the active slide E associated with the I finger key, so that this active slide through the medium of the connected trip dog E ,cam yoke E and reed E causes the actuation of the escapement E? acting in the magazine. channel occupied by matrices X bearing the letter I, and now containing matrices Z bearing'the letter r. The connections from the other keys may be traced in like manner, it beingapparent that in each instance the bails serve to permit the finger keys to cooperate with matrix columns in the magazine offset from or located to one side of the corresponding finger ke s.

dhe bails E thus indicated diagrammatically in Fig. 19 are shown in their mechani-- cal embodiment in Fig. 12, but in the figure, the active slides E are in engagement with the finger keys so that the bails. are idle. It can be seen,.however, that when the slides are shifted to the left to engage the finger keys'with the free slides E the bails will also become engaged with such slides and will connect them with the active slides of other pairs marked 6 i h z 7 l P Z, respectively, to denote the finger keys with which they are associated, or'with which they are on aged in the other position of the slides.

t will now be clear that by merely shifting the slides E, E laterally in one direction or the other, the keyboard may be'operatively connected to a magazine containing a font of matrices X or a magazine containinga font of matrices Z, not withstanding the difference in the number and arrangement of the characters in these fonts. However, to make the operation entirely clear,

referencemay be had to Figs. 16 to 18 which a u as required in effecting the release of mat e finger key, offset to they the corresponding bail E in the magazine, and that rices X bearing the same letter. At this time, the bail E is idle, being engaged at one end in the widened notch e of the slide E, and at its other end in the notch e of the free slide E which of course is disen aged from its corresponding finger key. hen, now, the slides are shifted to their other position, as shownin Fig; 18, the R finger key is disengaged from its active slide E and, engaged with the companion free slide E, which latter is connected my means of the bail E with the active slide E of the finger key for the hyphen, so that the actuation of the R finger key will result in the operation of the cam yoke of the otherkey, as required in effecting the release of matrices Z bearing the letter R.

It will also be noted that, in the latter position of the parts,the finger key bearing the numeral 8 (representative of the keys not used for the matrix fonts Z) is also engaged with its free slide E, but since no bail is associated with such slide, the finger key is disbonnected from any oneof the camyokes and hence will have no effect upon the other parts if it should be accidentally actuated. As a matter of fact, at such time the finger key will be positively locked against action by means later to be described. However, when the partsare in the first position, this numeral finger key will be engaged withits other slide E, which is actively connected to the associated cam yoke, so that its actuation at that time will effect the proper release of the corresponding matrices X of the other fonts.

' It will be seen, therefore that in effecting the release of the matrices X from the megazine, all the escapements are actuated'by the keyboard, whereas in effecting the release of the matrices Z, some of the finger keys (seventeen of them), and hence as many dif the releaseof the matrices of another font (the matr ces X), the means before de-- scribed acting to permit or prevent the conjoint operation of said groups as re uired'. In this connection, however, it will e remembered that the matrices X and Z are. arranged in a different order as to character the operativeconnections between the keyboard and the magazine are such as to enable the finger keys when actuated to effect the release ofmatricesbearmg the same character irrespective
